I'm studying B-17 engineering drawings and finding references to threads I have no knowledge of.
Is anyone familiar with the thread standards of the time please? I'm looking specifically for thread major and minor dimensions.
The kind of refs I'm seeing are:
11/16-24 NS-2
1 15/16-16 NS-3
2 7/16-16 N-3
1-14 NF-3
There seems to be a common specification document for these threads which I haven't been able to locate: AN-GGG-S-126
Anyone out there that works on these old birds? Any help would be much appreciated.
Thanks!
